Abstract
A satisfiability modulo theories (SMT) solver accelerator is implemented with analog content addressable memory (CAM) cells. A job-shop scheduling problem (JSSP) may be mapped to expression clauses that are stored in an analog CAM array. A test cycle may be performed by searching for a test vector of input variables in the analog CAM array, selecting a candidate variable of the test vector that is violating a largest number of the expression clauses, and changing the candidate variable of the test vector. The test cycle may be repeated until none of the expression clauses are violated by the test vector of the input variables. The resulting test vector of the input variables that violates no expression clauses is a solution for the JSSP.
